Forge errors. help please

[elfruler]

Hi our server is running

Minecraft 1.4.2

Forge 6.0.1.341

PlayerAPI Universal 1.1

Smart Moving 11.5

 

Our server has started having sever lag and will only clear up for about 30 mins after a reboot. Any help would be appreciated. Our server host keeps seeing the following errors in the log.
